Cosmos -Mysterious Black holes

welcome back if you are here again, and hello if you are first time
for the first times, i hope you know what is black hole
because to know the mystery of black hole, you have to actually know what is exactly black hole.

to put in simple and pure words, black is nothing but a very densely packed mass of gasses and dust, which has so high magnetic field that nothing can escape it, not even light, well, when you read this line, i am making an understatement.
you should get this in your head very loud and clear that even light cannot escape from black hole.
think about it, isnt this like some amazing fairy tale?
well if you get that kind of feeling right now, i would like to welcome you to the universe
welcome to the world since you have taken some time out of your busy schedule :)

in last few post, i mentioned how black holes are formed, to brush that a little, lets revise it point wise
black holes are formed because
1:heavy initial mass of star
2:burning out of fuel
3:supernova
4:compression due to gravity to extreme condition

so these factor determine or tell the story of formation of a black hole
a black can be termed as goon of our universe, like some gangster on loose...who will destroy everything that comes in its way.
and goons are always bad.
what makes them bad? why are they bad? they destroy things that's why?
no thats not the only one reason, but sure its one of the major reason
black holes are, as i earlier said,mass of highly packed gas and dust, today i would like to refine my statement, which would remind you that it is actually a dead star
black holes is mass of highly packed debris of dead star. sounds spooky to me :P
anyway, its actually debris of whats left from star when it die, how?
well see this, a star massive in size, so powerful that it liberates the same of amount of energy in one second as sun take a year to give. and that all, a star which is tens and thousand times bigger than sun itself, just guess the size, what would be like to stay in a solar system with such star and have it as sun, better be the ninth planet for it :P

when star run out of fuel, it extinguishes, what left is lithium or carbon or any higher atmoic number bearing metal in periodic table
for e.g lets assume that its made of carbon
okay, so here we have so much carbon that its ball was many times bigger than sun, suddenly after its off, the whole mass is concentrated not bigger than the sun,in fact many times smaller than sun.
such is the density, such is the compactness, such is the gravity inside.
and this dudes, is the real culprit.
this gravity due to the awesome mass collapsed, is so strong that it simply devourers anything that might be in its way and still be hungry for more. till date never anyone has seen a black hole dying, we have just seen them eating, gobbling up planets-suns-stars-and even galaxies
dont be surprised, there is more to add to this.
have you seen carefully to a glass of water when you stir it with spoon?
what happens?
a vortex is created, right
well imagine something like that big rotating at very high speed, what will be size of vortex
but wait here, aint i wrong about vortex, here on earth when you stir water, you are actually stiring the whole medium, and in space there is no medium, so how can a vortex be there?
when a black hole is revolving it too creates a vortex and the vortex are at its poles, the poles on which it is spinning
this vortex is made up of dust and gas which black hole once devoured, x-rays, u-v's, radio waves and cosmic waves
and believe it or not, these vortex are so long, sometimes even span through and through a galaxy

these vortex are so large and powerful that they can even destroy a galaxy from light years of distance
but these are less destructive from the hunger and striving of the black hole. its mass keeps increasing and hence gravity
nothing can ever come out of it. on earth we know that speed of light is so very fast, plus its not made of particle so we cant make a device which can bend light except change the medium, not by attraction
if ever we created it, it will first destroy our planet by attracting everything, including the hot-molten-iron-lava inside, and turning whole planet upside down, well we will talk about it later, light, focus on light.
bottom line we cannot bend light by attraction, but black holes can, there force of gravity is such that it not only bends light but even absorbs it all the way.
your next question must be that, if they dont have there own light (as then name suggest-black) and they dont reflect light visible to our eyes, then how the hell are they detected at first place.
black holes are not pinned at one place, they move, and we humans have a big keen eye up there called Hubble telescope, it keeps 24X7, 365days its eyes looking for changes, when astronomers find that there was a no stars visible in that area and after few years suddenly becomes visible, they match years of photographs and then after there finding they declare that there might be/is a black hole there, destroying things.
such are black holes detected in space.

but i too am still wondering about a fact,
we know that light is energy, infact every thing in this universe is energy as per Einstein energy and mass are inter-convertible, so where is this energy going.....is it being converted into mass, if yes, what kind of mass is that?
what metal/non metal it converts itself?
what will happen when the mass increases like anything and it again becomes very big o initial size but huge mass.
my question is only, 'then what?'

we dont know yet, if you think you know, tell me as well,
why we dont know because our time frame is much smaller than that of stars, like we see moths, they are born and die on same day, there lifepsan is of 24hrs, but from there perspective they are born, become adult, mate and give eggs, and then die, for then we, humans are like those stars to us,, eternal-immovable-dormant-mysterious etc etc
so we have to wait for years, maybe decades, maybe centuries to get an answer of what might be happening to black holes...........

what might happen?
